It is simple to operate yet delivers outstanding performance and reliable results, for even the most challenging experiments. You can produce both rich, detailed, chemical images and highly specific data from discrete points. With unparalleled flexibility, scientists and engineers, worldwide, trust the inVia microscope.

Features

The inVia microscope comprises a research-grade microscope coupled to a high-performance Raman spectrometer. It is simple to operate yet delivers outstanding performance—high signal throughput, combined with high spectral resolution and stability—giving reliable results, for even the most challenging measurements.

The inVia microscope’s highly efficient optical design produces the best Raman data, even from minute traces of material. If you need to easily and reliably produce both rich, detailed, chemical images and highly specific data from discrete points, then the inVia microscope is the ideal system for you.

Speed and sensitivity

High sensitivity enables you to look at weak Raman signals and rapidly analyse even minute traces of material, monolayers and weak scatterers. It uses a stigmatic on-axis optical design which provides high optical efficiency, excellent stray light rejection and unparalleled sensitivity.

High spatial resolution

The optical design enables you to achieve a very high level of confocality (the ability to reject signal from regions away from the point of interest). This ensures you achieve high stability and the highest spatial resolutions possible, limited only by the inherent diffraction limit of the light.

High spectral performance

It can resolve spectral features narrower than 0.5 cm-1, so you can distinguish between close Raman bands, and differentiate very similar materials, such as pharmaceutical polymorphs. High stability allows you to monitor minute shifts in Raman band position (as low as 0.02 cm-1).

Exceptional stability

A custom designed honeycomb baseplate holds the inVia microscope and lasers in position and is so stable that an optical or anti-vibration table is not normally required. Key moving components are equipped with Renishaw high precision encoders which ensures everything is correctly placed.

Spectral flexibility

You can configure the inVia microscope so that it is ideal for analysing your particular samples. It supports multiple lasers with automated computer-controlled switching. You can change excitation wavelength rapidly and quickly determine the best configurations to get reliable data from all your samples.

Sampling flexibility

inVia supports both research-grade upright, inverted and open frame microscopes, as well as fibre optic probes for long distance remote analysis. It is compatible with a range of objective lenses and environmental cells enabling you to analyse your samples under a variety of environmental conditions.

Maintain focus in real time with LiveTrack

The inVia microscope uses LiveTrack™ automated focus tracking technology to acquire, in real-time, accurate and repeatable spectra and topography from samples with extensive variations in height. Create stunning 3D images of uneven, curved or rough surfaces without the need for pre-scanning.

Analyse liquid or gas samples easily with the macro sampling kit

The macro sampling kit makes it easy to analyse liquid or gas samples in vials and cuvettes. Installed in seconds, it helps to get your Raman analysis done quickly.
